[0001] The utility model relates to a plastic woven bag cutting device, belonging to the technical field of bag cutting equipment. Background Art

[0002] Plastic woven bags are a widely used storage item and play an important role in chemical production, construction materials, breeding and other industries. They can facilitate the transportation and handling of various raw materials and avoid scattering during transportation. In the production process of plastic woven bags, most of them use automated production equipment. This production method is more efficient. However, when data errors occur, a large number of bag raw materials of different sizes are often generated. Once the automated equipment suffers a power outage or malfunction, these bags of different sizes often need to be manually cut one by one.

[0003] Publication number: CN214686766U, mentions a plastic woven bag cutting device, which is equipped with a manually operable cutting structure and can achieve quick size trimming of a certain number of plastic woven bags through simple manual adjustment, thereby solving the production needs during power outages or equipment failures, and can trim bags produced by automated equipment that do not conform to the batch size, thereby reducing the labor intensity of manual trimming. However, due to the low hardness of the woven bags, wrinkles are prone to occur during the transmission process. The device directly trims the bag body, which can easily cause uneven cutting when the woven bags are cut, affecting the quality of the woven bags. Now there is an urgent need for a plastic woven bag cutting device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3The utility model provides a technical solution: a plastic woven bag cutting device, comprising a bag cutting base plate 1, a step slide shaft 6 and a cutting tool holder 16, the front and rear ends of the bag cutting base plate 1 are fixed with an elliptical guide frame 2, the front and rear positions of the upper right side of the bag cutting base plate 1 are symmetrically fixed with bending pieces 3, the upper ends of the two bending pieces 3 are screwed with hand bolts 4, the step slide shaft 6 is on the upper side of the bag cutting base plate 1, and the front and rear ends of the step slide shaft 6 are respectively slidably inserted into the two elliptical guide frames 2, the front and rear sides of the right end of the step slide shaft 6 are fixed with arc-shaped fixing pieces 8, the lower sides of the right ends of the two arc-shaped fixing pieces 8 are fixed with fixing strips 9, the upper ends of the two fixing strips 9 are fixed with a first magnet strip 10 by epoxy resin glue, the middle of the right ends of the two arc-shaped fixing pieces 8 are integrally fixed with a convex strip plate, and the middle of the upper ends of the two convex strip plates are slidably inserted with a pull rod 14 , the lower ends of the two pulling rods 14 are horizontally fixed with moving bars 13, and the lower ends of the two moving bars 13 are fixed with second magnet strips 12 by epoxy resin glue. The cutting tool holder 16 is installed on the upper ends of the two elliptical guide frames 2, and a bearing seat 22 is installed through the middle of the cutting tool holder 16. The inner ring of the bearing seat 22 is longitudinally fixed with an inner screw barrel 20, and the upper sides of the front and rear ends of the inner screw barrel 20 are fixed with swing handles 21. A threaded rod 19 is inserted into the inner screw barrel 20 through the thread principle, and the lower end of the threaded rod 19 is connected to the cutting blade 18, and the cutting blade 18 is longitudinally in the cutting tool holder 16. The front and rear sides of the upper end of the cutting blade 18 are longitudinally fixed with guide bars 17. This design solves the problem that the original device directly trims the bag body, which easily causes uneven cutting when cutting the woven bag, thereby affecting the quality of the woven bag.

[0020] As the first embodiment of the present invention: the lower ends of the two hand-tightening bolts 4 are provided with limiting retaining plates 5. The added hand-tightening bolts 4 and limiting retaining plates 5 facilitate the limiting and fixing of the front and rear ends of the right end of the woven bag. A handshake groove is provided on the left side of the upper end of the step slide 6. The added handshake groove facilitates the staff to pull the step slide 6 to move horizontally. Arc-shaped plastic blocks are symmetrically fixed to the lower ends of the left and right sides of the step surface of the step slide 6, and universal ball bearings 7 are installed at the lower ends of multiple arc-shaped plastic blocks. The rolling ends of multiple universal ball bearings 7 slide against the lower sides of the two elliptical guide frames 2. The rolling ends of the added multiple universal ball bearings 7 slide against the lower sides of the two elliptical guide frames 2, which can prevent the step slide 6 from rotating inside the two elliptical guide frames 2. Multiple anti-slip bumps 11 are adhered to the lower ends of the two second magnet strips 12, and the multiple anti-slip bumps 11 are respectively located directly above the two first magnet strips 10. By adding multiple anti-slip bumps 11, when the front and rear ends of the left end of the woven bag are stuck between the two first magnet strips 10 and the two second magnet strips 12, the contact part with the woven bag can be tightly adhered.

[0021] Restoration springs 15 are longitudinally mounted between the two movable bars 13 and the two protruding strips. The addition of multiple restoring springs 15 allows the two movable bars 13 to be pushed downward, forcing the two second magnet bars 12 to move downward. Two guide bars 17 slide through the front and rear ends of the upper end of the cutting blade holder 16, respectively. This prevents the cutting blade 18 from shaking when it is driven to move vertically.

[0022] As a second embodiment of the present invention: when the automatic cutting equipment is powered off and the wrinkled woven bag needs to be flattened and cut, the front and rear ends of the right end of the woven bag are respectively placed under the two bending pieces 3, and then the two hand-tightening bolts 4 are screwed so that the two hand-tightening bolts 4 pass through the two bending pieces 3 and rotate downward, thereby driving the two limiting retaining pieces 5 to rotate downward until the two limiting retaining pieces 5 are tightly against the front and rear ends of the right end of the woven bag, and then the two pulling rods 14 are pulled upward to move the two moving bars 13 upward, forcing the multiple reset springs 15 to compress, and the two first magnet strips 10 and the two second magnet strips 12 will also separate, and then the front and rear ends of the left end of the woven bag are placed on the upper ends of the two first magnet strips 10, and then the two pulling rods 14 are released, and the multiple reset springs 15 reset downward, pushing the two moving bars 13 to move downward, and driving the two second magnet strips 12 The magnet strip 12 moves downward until the two second magnet strips 12 pass through the multiple anti-slip protrusions 11 and the woven bag is magnetically attracted to the two first magnet strips 10. At this time, the multiple anti-slip protrusions 11 will also be in close contact with the front and rear ends of the left end of the woven bag. Then, hold the handshake groove and pull the step slide shaft 6 to the left. During this process, the woven bag will be flattened and unfolded. Then, turn the multiple swing handles 21, and the inner screw barrel 20 will rotate in place in the bearing seat 22, and the threaded rod 19 will also be mobilized and moved downward through the thread principle, thereby driving the cutting blade 18 to move downward until the cutting blade 18 cuts the left side of the upper end of the woven bag. During this process, because the two guide bars 17 slide through the front and rear sides of the upper end of the cutting tool holder 16 respectively, the threaded rod 19 will no longer rotate inside the inner screw barrel 20 and will only move downward, which also makes the cutting blade 18 more stable when it is driven to move up and down.
